They all have their merits

I can currently hold down a key (del or f12?) when powering on to choose between the Linux disk and the Windows disk, that’s my current dual-boot setup. I also installed each one with the other disk disconnected. I remember the Windows update rebooting into Linux unless I interrupted it too.

You say Windows was on a separate drive, but then you talk about dual booting. Do you mean that Windows was on another partition on a shared drive, or do you have two separate hard drives?

I assumed dual booting just means having multiple OSs installed, does it specifically mean having them on the same disk? I have separate disks, so hopefully no need for partitioning shenanigans.

What problem are you trying to solve?

Partly redundancy, if I mess up one then I’ve still got the other; partly for supporting people, I’ve set up non-techies on both and I want to be able to load up the same system myself when I need to help them.
